Week 4: Clear

This weeks topic that was most clear to me was images, and in particular native vs. interpolated resolution. Some imaging devices such as digital camera's and scanners will advertise an artificially high resolutions due to their resolution boosting interpolation programming. The native resolution is actual gathered data from the image whereas the interpolated resolution fills the space between two real pixels with an average of the two which will create a blurring effect when the colors are strongly contrasting.

I think that it is particularly important for businesses to know whether their copiers and scanners use native or interpolated resolution because it could cause a problem if the exact resolution is needed in a copy, such as in maps or detailed drawings.

I found an interesting website that had much to add about interpolation and its benefits/drawbacks. The website http://www.scantips.com/basics07.html had a very interesting write-up about interpolation, particularly in scanning devices. The most important thing that the website had to say in my opinion was that interpolating does not add detail, only filler.
